Géziyāndūn
Geziyandun is a ruined beacon and postal station in the desert east of the Hami oasis. It stood along a route through the dry country between Hami and the eastern approaches to the Western Regions, where a chain of watchposts helped carry warnings and maintain communications. The site preserves traces of both a signal tower and a station, bringing together military watchfulness and the practical needs of travellers on the long desert road.
